GamePro digs deep for PSP Slim pet peeves
Their main complaint is how the d-pad is smooth, thus making it susceptible to sticky thumb syndrome. Other complaints involve the UMD slot metal tabs being easily bendable, too many inputs slots (they would rather an iPod-esque single input), and plastic bezel instead of the metal one used on the older PSP.
The fact that these are GamePro's four main gripes about the system is a testament to how well designed the new system is. We've been looking in-depth at our PSP-2000, and again, and once more for good luck, and have not found anything too alarming. If you were lucky enough to find a PSP Slim Daxter bundle, feel free to share your pet peeves with the rest of the class.
